Hide an exe inside my compiled script?

Hi,

I'm working on a script right now that uses an old exe tool's command line functions. Basically I'm using AutoIT to build a GUI for an old command line tool. The script works fine with the exe next to my script in the folder but I was wondering if there was a way to include the tool inside my compiled AutoIt script so that in the end I only have 1 exe that I can distribute around?

Thanks!
